UnrrEn sra rns PATENT urio A v i panama nunrna orgsnssntmn, are nam ng l i I 1,035,090, Specification of Lettersil'atent, I 'No Drawingr and to a process for preparing the same, and

1 the invention particularly consists of a comosition consisting of the ingredients herelnafter set fortl1, suitable' for use in mending all kinds of Cl'llIl'iL ware, porcelain, glass, and leather. y

The object of invention is toproduce an adhesive for the purpose above named, which can be compounded by employing only-inexpensive materials, which .will set quickly when applied for use, will resist the action of Water and heat, and which will not crack when hard.

Theconstituent ingredients of the adhesive'are as follows, the first three named serving as-the foundation sticky mixture, {5 and the remaining compounds being employed for purposes hereinafter described 2 acetic acid,'water, isinglass, plaster of Paris, common salt, and sulfate of zinc.

I have discovered that a mixture of plas- 'ter of Paris, commons-alt, and sulfate of zinc,--added to isinglass dissolved in acetic acid and water, causes such an adhesive formed by to set quickly to the article I Furthermore. I have Paris and sulfate of when the adhesive is applied which it is desired to mend. found that plaster of zinc added to such an adhesive mixture causes the same when applied to resist the action of .water and'heat. 40 I have also fo'undt-hat a gelatinous material,

such as isinglass, will not crack when hardened when sulfate of zinc is added thereto.

I will now proceed to .describe the exact manner in which the constituent ingredients of the adhesive forming the present invention are compounded. To a quantity of glacial acetic'acid of 99%, I add of water, after which I heat the resulting liquid to a temperature of 160 degrees F. I then 50 compound a mixture consisting of two parts plaster of Paris, two partssulfate of zinc, and one part common'salt. I mix these last damed substances'toabatter with some of the liquid consisting of the acetic acid and water. This batter is then, added to the. rest of the liquid. at the names-time stirring the Application filedllllarch 13,1915.

mixture, the. quantity! of} the mixture of plastercfParis, sulfate of zinc','and common salt used being about of a pound'to eacli' gallon of liquid. To the liquid towhich said mixture has'been added, I then addabout 4 pounds'of French isinglass to every" gallon of liquid, stirring the liquid as the isinglass is added. The adhesive produced in. this manner will now be ready for use. 5 The ising'lass dissolves in the acetic acid, and thus the main adhesive body is formed.

of Paris, salt, and sulfate of'zinc causes the adhesive to set quickly when applied for use, and I have found an, especially advantageous action in this regard when. these substances are, used in substantially the proportions set forth. The plaster of Paris and the sulfate of zinc render the adhesive .vater-resisting and enable it to withstand the action of heat. and the sulfate of zinc has the property of preventing the adhesive from cracking when it has hardened. These properties of the materials named have not been known heretofore. v

The adhesive formed according to the present invention is excellent for securing together the parts of broken china and glass ware, porcelain, leather, and materials of,8 5 like nature. I

Having t us described the said invention, what is claimed as'new is 1. An adhesive compound consisting of acetic acid, water, isinglass, plaster of Paris.

sulfate of zinc, and common salt.

2. An adhesive compound consisting ofrelatively large quantities of acetic acid, isinglass, and water, and containing relatively small quantities of a mixture consisting of two parts of plaster of Paris, two palrts sulfate. of zinc, and one part common.

3. An adhesive compound consisting of the following. constituent ingredients acetic acid of- 9970' water, isinglass, plaster of Paris, sulfate of zinc, and common salt,

in the proportions of 9; pound of the three last named ingredients and 4% pounds of isinglass to substantially one gallon of acetic 10 acid and water.

4. Process of producing an adhesive compound, which consists in adding water to acetic acid, heating the liquid, then forming a mixture consisting of plaster of Paris, sulfate of zinc, and common salt, and adding the same to the liquid while stirring. and

sulfate of zinc,

then add ng isinglass to the liquid While stirring.

5. Process of producing an adhesive compound which consists in adding water to strong acetic acid, heating the mixture to a'temperature of about 160 degrees F., then forming a mixture consisting of substantially. two parts plaster of Paris, two parts mixing'the same to a batter with a portion of the liquid before referred to, then adding and one part common salt,

said batter to the liquid at the same time stirring the same, then adding about 4% pounds of isinglass to every gallon of the liquid so formed and stirring the same.

In testimony whereof I aflixmy signature in presence of two Witnesses.
